Winter can be snowy and very cold but also rainy, with many temperature fluctuations around the freezing point. In each case, your lawn is exposed to significant stress.
Snow itself does not affect a properly cared lawn, but it can favor various problems and diseases.
As a measure of precaution, you should not step on the lawn as long as it is frozen and covered with snow. Also, make sure you remove the leaves that fall from the trees in autumn; do not make piles and leave them there and apply organic lawn care products to nourish your lawn for winter. Making piles of snow is also a mistake, because they favor the apparition of snow mold, which is a type of fungus that destroys lawn areas. This disease occurs mainly in areas that have not been trimmed before the winter, and where leaves and snow blocked the proper aeration for a long period.
Like other pathogen-causing diseases, snow mold pathogens are always there, but the disease erupts only if there are conditions for its development.
A well-groomed lawn is typically more resistant to snow mold. For this reason, proper lawn care is the best method to prevent this disease. During the year, regular lawn aeration, fertilization and monitoring are recommended for optimal protection in the cold season.
